Description

Aerosol generating system with aerosol generating device and operation button protection function

The present invention relates to electrically operated aerosol-generating systems, and in particular to electrically-operated aerosol-generating systems having an aerosol-generating device and a charging device for housing and charging the aerosol-generating device.

Electrically operated aerosol-generating systems typically include an aerosol-forming substrate and a nebulizer, wherein the nebulizer is operated to nebulize volatile compounds within the aerosol-forming substrate to form an aerosol for inhalation by a user. Typically, the electrically operated aerosol-generating system also includes an aerosol-generating device that includes a power supply for powering the nebulizer. The nebulizer may be an electrically operated heating means, for example an electric heater.

In some systems, the aerosol-generating device is configured to receive an aerosol-generating article comprising a solid aerosol-forming substrate, such as a substrate comprising homogenized tobacco. In such systems, the device includes a nebulizer, typically arranged to heat the aerosol-forming substrate when the article is received within the device. The article may also include a filter wrapped with an aerosol-forming substrate in the form of a rod similar to a conventional cigarette. In some systems, the aerosol-generating article may include a cartridge containing a liquid or gel aerosol-forming substrate that can be heated by a nebulizer. In some systems, the device can be configured to receive a cartridge containing both a nebulizer and a liquid aerosol-forming substrate. These cartridges are often referred to as cartomizers. A typical configuration of atomizers used in cartomizers includes a coil of heater wire wound around an elongated wick immersed in a liquid aerosol-forming substrate.

Some electrically operated aerosol-generating systems include a separate charging device to recharge and keep the aerosol-generating device releasable when not in use. These charging devices can also function as cases or holders and provide some degree of protection for the aerosol-generating device. The filling device can also provide additional functionality, such as data-logging and refilling the aerosol-generating device with an aerosol-forming substrate.

Aerosol-generating devices typically have a high aspect ratio with a first, longitudinal dimension that is larger than the second and third width dimensions. Cases for holding aerosol-generating devices often include a housing that defines a narrow opening into which a user needs to insert the device. The narrow opening typically has a width similar to the width of the aerosol-generating device. Users inserting aerosol-generating devices into these cases are generally required to insert the aerosol-generating device into the case by closely aligning the aerosol-generating device with the narrow opening and then slide the aerosol-generating device longitudinally into the case. This can be difficult for the user, especially in low light or when the user is moving. The aerosol-generating device may include one or more user operation buttons, generally located on the body portion or housing portion. By sliding the entire aerosol-generating device into the cavity, the button can be protected from unintentional activation, but the button remains non-functional for much of the time thereafter.

It would be desirable to provide an aerosol-generating system that improves the speed and ease with which a user can insert an aerosol-generating device into a compatible charging device and remove the aerosol-generating device from the charging device without risk of inadvertent or improper activation.

An electrically operated aerosol-generating system can be provided that includes a charging device comprising a primary power source, and an elongated aerosol-generating device comprising a secondary power source. The aerosol-generating device has a proximal end, a distal end, and a body extending between the proximal and distal ends. User operation buttons are located on the body between the proximal end and the distal end.

The aerosol-generating system can be described as having a first state of engagement in which the aerosol-generating device is engaged with the charging device and a second state of engagement in which the aerosol-generating device is not engaged with the charging device. For example, in a first engaged state, the aerosol-generating device can be charged by the charging device and in a second engaged state, the aerosol-generating device can be separated from the charging device and used to generate an aerosol. When the system is configured in the first engaged state, at least a first side portion of the body extends between the proximal end and the distal end of the aerosol-generating device, and at least a first side portion of the body extending between the proximal end and the distal end of the aerosol-generating device. 2 The side part faces away from the charging device. The second side portion is exposed. The second side portion can be approached or touched by the user when the system is in the first engaged state and when the system is in the second engaged state.

A user-operated button can be any means for activating or activating a feature or function of the aerosol-generating system. For example, a user-operated button can act as a switch to initiate a thermal cycle for the creation of an aerosol. The user-operated button may have a mechanical element, for example the user-operated button may be a push button that activates a feature or function. The user-operated button may utilize different types of actuation, for example electrical or optical sensing, or magnetic sensing. The aerosol-generating device includes at least one user operation button. The aerosol-generating device may include more than one user-operated button, for example two buttons or three buttons, located on the body between the proximal end and the distal end.

At least a second side portion of the aerosol-generating device is directed away from the charging device and is exposed to the external environment when the system is in the first engaged state. Because at least a second side portion of the body of the aerosol-generating device is exposed, a user can interact with the aerosol-generating device even when the system is in the first engaged state. Accordingly, the user can hold the aerosol-generating device and quickly and easily remove it from engagement with the charging device. Additionally, the user can see indicator means, such as an indicator light, located on the second side portion of the body when the system is in the first engaged state. These indication means will otherwise be redundant when the system is in the first state of engagement.

The user operation button may be located on the first side portion of the main body. At least a first side portion of the aerosol-generating device is shielded or protected because it faces the charging device when the system is in the first engaged position. In this configuration, the user operating buttons will be shielded or protected from accidental actuation when the system is in the first engaged state and the aerosol-generating device is charged by the charging device. If the aerosol-generating device includes more than one user-operated button, it may be desirable for at least one user-operated button to be located on the first side portion of the aerosol-generating device, preferably each or all user-operated buttons It is located on the first side portion of the generating device. The part of the charging device facing the aerosol-generating device may be configured with a recess or recesses to receive a user operation button or a respective user operation button. Accordingly, the button or buttons can be protected from accidental activation when the aerosol-generating device is engaged with the charging device. The user operable button may be located within a recess in the body of the aerosol-generating device so that the button or buttons can be protected from accidental activation when the aerosol-generating device is engaged with the charging device.

The user operation button may be located on the second side portion of the main body. At least a second side portion of the aerosol-generating device is exposed as it is directed away from the charging device when the system is in its first engaged position. In this configuration, the user operation button can remain accessible to the user when the system is in its first engaged state and the aerosol-generating device is being charged by the charging device. If the aerosol-generating device includes more than one user-operated button, it may be desirable for at least one user-operated button to be located on the second side portion of the aerosol-generating device, preferably each or all user-operated buttons It is located on the second side portion of the generating device.

If at least one user operation button is located on the second side portion of the body, it may be desirable for the user operation button to be deactivated when the aerosol-generating system is in the first engaged state. For example, the system may detect engagement between the aerosol-generating device and the charging device and disable user-operated buttons to prevent accidental activation while the aerosol-generating device is engaged with the charging device. Accordingly, the system obtains the advantage of having at least a portion of the aerosol-generating device exposed without the risk of accidental activation of one or more functions of the aerosol-generating device.

If at least one user operation button is located on the second side portion of the body, it may be desirable for the user operation button to be activated when the aerosol generating system is in the first engaged state.

If at least one user operating button is located on the second side portion of the body, it may be advantageous for the user operating button to remain operable when the aerosol-generating system is in the first engaged state. For example, the button may activate data transfer between the aerosol-generating device and the charging device, and it may be advantageous for the button to be activated when the system is in its first engaged state.

Advantageously, the user-operated button can activate the first function when the aerosol-generating system is configured in the second engaged state, and the same user-operated button can activate the first function when the aerosol-generating system is configured in the first engaged state. Different secondary functions can be activated. Thus, for example, a button may activate a heating cycle to generate an aerosol when the aerosol-generating system is configured in the second engaged state, but the same button may activate a cleaning cycle when the aerosol-generating system is configured in the first engaged state. , for example, a heater may be heated to a high temperature to activate a cycle that pyrolyzes the contaminating material. remind

The system preferably detects engagement between the aerosol-generating device and the charging device and reassigns the functions of the user operation buttons to allow different functionality when the aerosol-generating device is coupled to the charging device. By this means, fewer buttons are required in the system and the buttons on the aerosol-generating device may not be duplicated when the aerosol-generating device is connected to the charging device. Additionally, a user operating button located on the aerosol-generating device can be used to control the functions of the charging device when the system is in the first engaged state. Therefore, there are fewer buttons or no buttons are needed on the charging device. The charging device may not have operation buttons. Operation of the charging device can be facilitated by using a button located on the aerosol-generating device when the aerosol-generating device is engaged with the charging device.

One or more buttons, contacts or displays may be located on an external part of the housing of the charging device, wherein the one or more buttons, contacts or displays are shielded by the aerosol-generating device when the aerosol-generating system is configured in the first engaged state. Accordingly, the functional features of the charging device, such as buttons, contacts and displays, can be hidden and protected when the charging device is engaged with the aerosol-generating device.

Advantageously, the electrical contact can be located in the first side part of the body. The contact may be configured to couple to a corresponding contact on the charging device for passage of current or data when the system is configured in a first engaged state.

Advantageously, the visual indicator can be located on the second side part of the body. The visual indicator may be a status light or display that can be seen when the system is configured to the first engaged state.

The charging device may have a docking arrangement configured to engage with the aerosol-generating device. The docking arrangement may include a locking space defined between the first end and an opposing second end spaced from the first end and secured to the first end, the docking space comprising an elongated aerosol device between the first end and the second end. It may include a docking space to accommodate the longitudinal dimensions of the generating device. At least a portion of the aerosol-generating device remains exposed when the aerosol-generating device is engaged with the charging device. For example, at least one side of the body of the aerosol-generating device can be exposed when the aerosol-generating device is engaged with the charging device, forming an external surface of the aerosol-generating system.

Advantageously, the engagement between the aerosol-generating device and the docking arrangement can be effected by relative movement of the aerosol-generating device and the docking space in a direction perpendicular or substantially perpendicular to the longitudinal axis of the aerosol-generating device. A docking space may be defined between the first end and an opposing second end spaced from the first end and secured to the first end to accommodate the longitudinal dimensions of the elongated aerosol-generating device. The aerosol-generating device has a longitudinal dimension defining a longitudinal axis, and the charging device can have a docking arrangement configured to engage the aerosol-generating device for charging the secondary power source by the primary power source. Optionally, engagement of the aerosol-generating device and the docking arrangement may be effected by engaging a first engaging member located on a side wall of the aerosol-generating device with a second engaging member located on a wall of the charging device. The coupling member may include a plug and a socket. The coupling member may include an electrical contact, such as an electrical contact that includes an electrical connection that allows the secondary power source to be charged by the primary power source.

Preferably, the first end and the second end form part of the charging device, for example forming part of the housing of the charging device. The first end and the second end may be walls of the housing of the charging device. The first end and the second end may be members extending from the housing of the charging device. Preferably, the docking space is at least partially external to the charging device. For example, the docking space may be open to the environment external to the charging device when the aerosol-generating device is not accommodated within the docking space.

Preferably, the charging device includes a housing for maintaining a primary power source. The primary power source may be, for example, a rechargeable battery held by or within the housing of the charging device. Preferably, when the aerosol-generating device is received by the docking space, engagement between the charging device and the aerosol-generating device causes the secondary power source of the aerosol-generating device to be charged by the primary power source of the charging device. For example, electrical contacts located on the aerosol-generating device may be arranged to engage corresponding electrical contacts located on the charging device when the aerosol-generating device is engaged with the docking arrangement.

As used herein, the term ‘aerosol-generating device’ is used to describe a device that interacts with an aerosol-forming substrate to generate an aerosol that can be inhaled directly through the user's mouth and into the user's lungs. In certain embodiments, the aerosol-generating device can heat the aerosol-generating substrate to facilitate release of volatile compounds. The aerosol-generating device may interact with an aerosol-generating article comprising an aerosol-forming substrate or a cartridge comprising an aerosol-forming substrate. Electrically operated aerosol-generating devices may include a nebulizer, such as an electric heater, that heats an aerosol-forming substrate to form an aerosol.

As used herein, the term ‘aerosol-generating article’ refers to an article comprising an aerosol-forming substrate capable of releasing volatile compounds that are capable of forming an aerosol. In certain embodiments, an aerosol-generating article may comprise an aerosol-forming substrate capable of releasing volatile compounds upon heating, capable of forming an aerosol.

As used herein, the terms 'upstream', 'downstream', 'proximal' and 'distal' refer to components or parts of components of the aerosol-generating device, aerosol-generating article and case. Used to describe location.

As used herein, the term 'longitudinal' is used to describe the direction between a downstream, proximal or mouth end and the opposing upstream or distal end, and the term 'transverse' is used to describe a direction perpendicular to the longitudinal direction. It is used to

As used herein, ‘length’ means the maximum longitudinal dimension between the distal or upstream end and the proximal or downstream end of the components, aerosol-generating device, aerosol-generating article and case.

As used herein, the term ‘diameter’ is used to describe the largest transverse dimension of a component, such as an aerosol-generating device and an aerosol-generating article.

As used herein, the term 'cross-section' means a cross-section of the component, aerosol-generating device, aerosol-generating article and filling device in a direction perpendicular to the major axis of each of the component, aerosol-generating device, aerosol-generating article and case. It is used to explain.

As used herein, the term “side portion” when used in connection with an elongated aerosol-generating device means that portion of the aerosol-generating device that extends longitudinally between the proximal end and the distal end of the aerosol-generating device. If the device's cross-section is polygonal, it may be easy to distinguish multiple side portions. For example, a device with a hexagonal cross-section would have six side portions. However, devices with a circular cross-section may have unclear side portions. For the purposes of this application, a side portion of a device having a circular cross-section will have at least four side portions, each side portion having a radial extent of no more than 90 degrees.

As used herein, the term ‘exposed’ is used to indicate that a feature or portion of a component is open to the external environment and is not enclosed or covered.

The term ‘magnetic material’ is used herein to describe materials that can interact with magnetic fields, including both paramagnetic and ferromagnetic materials. Because magnetisable materials are paramagnetic materials, they can simply remain magnetized in the presence of an external magnetic field. Alternatively, a magnetizable material may be a material that becomes magnetized in the presence of an external magnetic field and remains magnetized after the external magnetic field is removed (eg, a ferromagnetic material). As used herein, the term “magnetic material” encompasses both types of materials that are capable of being magnetized as well as materials that are already magnetized.

An elongated aerosol-generating device is configured to generate an inhalable aerosol from an aerosol-forming substrate. The elongated aerosol-generating device can be shaped substantially like a cigarette or cigar. For example, an elongated aerosol-generating device can have a first, longitudinal or longitudinal dimension that is larger in size than the second and third width dimensions. Although the second and third dimensions may be referred to as width and thickness, the second and third dimensions are preferably substantially equal and thus both may be referred to as width. The elongated aerosol-generating device may be substantially cylindrical. The longitudinal dimension defines the longitudinal axis. The width dimension extends perpendicular to the longitudinal axis. An elongated aerosol-generating device can be described as having a proximal end and a distal end, with an elongated body defined between the proximal and distal ends. The body may include at least one side extending between the proximal end and the distal end.

The docking space may be further defined by a rear portion extending between the first end and the second end. Accordingly, the docking space may be defined at least in part by a first end, a second end, and a rear portion. The rear portion may be the rear wall. The rear portion may be part of the outer wall of the housing of the charging device.

The aerosol-generating device can be easily engaged and disengaged from the docking arrangement by movement into the docking space in a direction perpendicular to the longitudinal axis of the aerosol-generating device, i.e. by movement transverse to the aerosol-generating device. The aerosol-generating device can be readily engaged and disengaged from the docking arrangement by movement into the docking space in a direction substantially perpendicular to the longitudinal axis of the aerosol-generating device. For example, the proximal or distal end of the aerosol-generating device can be inserted into engagement with a charging device within the docking space. The opposing end can then be pivoted into the docking space to fully engage the aerosol-generating device with the charging device. By using a vertical or substantially vertical movement, when inserted longitudinally into the filling device, less distance is required to be moved into engagement with the aerosol-generating device and the filling device than is the case with typical systems that accommodate the aerosol-generating device. The docking space of the charging device accommodates the longitudinal dimensions of the aerosol-generating device. If present, the opening into the docking space accommodates the longitudinal dimension of the aerosol-generating device. Accordingly, it is easier to position an aerosol-generating device within a docking space than if the docking space were dimensioned to accommodate only the transverse dimensions of the aerosol-generating device.

The docking space may at least partially form an open groove in the housing of the charging device. Accordingly, the docking space may be defined, at least in part, by a first side wall, a second side wall, a rear wall, and first and second ends. The opening groove may be an elongated recess or slot defined by the housing of the charging device. The elongated aerosol-generating device can be fully accommodated within the open groove such that no part of the aerosol-generating device extends beyond the peripheral boundary of the filling device. Alternatively, the elongated aerosol-generating device may be only partially accommodated within the open groove. In this case, the part of the aerosol-generating device, which can be termed the exposed part, extends beyond the peripheral boundary of the charging device.

It may be advantageous for a portion of the aerosol-generating device to form the outer surface of the system when the aerosol-generating device is engaged with the charging device. For example, it may be advantageous for at least one side of the body of the aerosol-generating device to form an external surface of the system when the aerosol-generating device is engaged with the charging device. The aerosol-generating device can be easily retrieved by the user who only needs to grasp the exposed portion of the aerosol-generating device and separate the aerosol-generating device from the charging device. The user can more easily maintain the exposed surface of at least one outer wall to facilitate separation of the aerosol-generating device from the charging device. The user may separate the aerosol-generating device from the charging device by grasping the exposed surface and applying pressure. Accordingly, the aerosol-generating device can be more easily recovered from engagement with the charging device.

The exposed portion of the aerosol-generating device may be shaped to match or correspond to the shape of the housing of the charging device. The charging device may have a shaped or contoured housing, and the aerosol generating device may also have a housing or outer surface configured to conform to the shape or contour of the charging device housing when the aerosol generating device is engaged with the charging device. The aerosol-generating device can act to close or cover open grooves within the filling device. Accordingly, charging device features such as displays, indicators, contacts or buttons located in these open grooves can be shielded from the external environment when the aerosol-generating device is engaged with the charging device. In this way, the display, indicator, contacts or buttons can be protected when the aerosol-generating device is engaged with the charging device, for example during transport.

At least 4 mm of the diameter of the aerosol-generating device may remain exposed when the aerosol-generating device is engaged with the charging device. This exposed portion may provide a surface for a user to grip the aerosol-generating device. Preferably, when the aerosol-generating device is engaged with the charging device, the diameter of the aerosol-generating device is at least 5 mm, for example at least 6 mm, or at least 7 mm, or at least 8 mm, or at least 9 mm, or at least 10 mm. mm remains exposed.

The charging device can define a docking space that is, at least in part, an open groove defined by a first side wall, a second side wall, a rear wall, and first and second ends. Portions of the first side wall or the second side wall or both the first and second side walls may be partially cut to expose more of the aerosol-generating device. Such cut wall portions can facilitate separation of the aerosol-generating device from the filling device by increasing the exposed surface of the aerosol-generating device in the area of the cut wall portion.

In some implementations, the first end and the second end are located on protrusions extending from the housing of the charging device, such as first and second protrusions extending from the housing. The protrusions may be named lugs. Accordingly, the longitudinal dimension of the docking space may be defined between opposing first and second ends located on the first and second protrusions. The docking space may not be constrained by any other dimensions. The aerosol-generating device engaging this docking space will only contact the first and second ends and, when engaged, will extend longitudinally between the protrusions. Alternatively, the docking space may be further confined by a rear wall extending between the first and second protrusions. The docking space may still be further confined by one or more side walls extending between the first and second protrusions.

The docking space is preferably configured to receive the aerosol-generating device when the aerosol-generating device is pressed into the docking space in a direction perpendicular to the longitudinal dimension of the aerosol-generating device. Accordingly, when engaged with the filling device, the longitudinal dimension of the aerosol-generating device is preferably parallel to the side or edge of the filling device.

The docking arrangement may include latching means, such as a mechanical latch, to releasably retain the aerosol-generating device engaged with the docking arrangement. For example, the latching protrusion may be configured to extend from the first or second end to engage a distal end or a proximal end of the aerosol-generating device. The latching protrusion may be biased away from the first or second end, for example by means of a spring. The latching protrusion may extend from the first or second end when actuated by a user. The latching protrusion may interact with a corresponding dimple, recess, slot or groove defined in the distal or proximal end of the aerosol-generating device. Mechanical latches may be positioned on both the first and second ends to releasably retain both the distal and proximal ends of the aerosol-generating device. Likewise, the proximal end, or the distal end, or both the proximal and distal ends of the aerosol-generating device may include a latching protrusion as described above, with the latching protrusion defined on the first or second end of the aerosol-generating device. may interact with corresponding dimples, recesses, slots or grooves.

The latching means may include one or more magnets. For example, the docking arrangement may include a magnetic latch to releasably retain the aerosol-generating device in engagement with the docking arrangement. One or more magnets may be positioned in the charger, for example in a portion of the charger, at or near the first or second end. The aerosol-generating device will then include one or more parts that are magnetically attracted to one or more magnets to keep the aerosol-generating device engaged with the charging device when the aerosol-generating device is aligned within the docking space. One or more magnets may be positioned in the aerosol-generating device, for example in a portion of the aerosol-generating device, at or near the distal end or the proximal end. The charging device will then include one or more parts that are magnetically attracted to one or more magnets to keep the aerosol-generating device engaged with the charging device when the aerosol-generating device is aligned within the docking space.

Magnets for latching may be included in both the charging device and the aerosol-generating device. A magnet of one of the charging device and the aerosol-generating device may provide a north pole and a corresponding magnet of the other of the charging device and the aerosol-generating device may provide a south pole. The aerosol-generating device may include a pair of longitudinally spaced magnets and the charging device may include a pair of corresponding magnets arranged to latch with the pair of magnets of the aerosol-generating device. A pair of longitudinally spaced magnets may be referred to as first and second aerosol-generating device magnets, and a pair of corresponding magnets may be referred to as first and second charging device magnets. The first aerosol-generating device magnet may be located at or near the proximal end of the aerosol-generating device. The second aerosol-generating device magnet may be located at or near the distal end of the aerosol-generating device. Both the first and second aerosol-generating device magnets may have a north polarity, in which case both the first and second charging device magnets will have a south polarity. If both the first and second aerosol-generating device magnets have a south polarity, then both the first and second charging device magnets will have a north polarity. If the first and second aerosol-generating device magnets are symmetrically spaced about the longitudinal midpoint of the aerosol-generating device, this arrangement can allow the aerosol-generating device to be latched with the charging device in either longitudinal orientation. In one arrangement, a first aerosol-generating device magnet may provide a north polarity and a second aerosol-generating device magnet may provide a south polarity. In this case, the first charging device magnet will provide a south polarity and the second charging device magnet will provide a north polarity. This configuration will cause the aerosol-generating device to be latched with the charging device when the aerosol-generating device is provided in a configuration such that the first aerosol-generating device is aligned with the first charging device magnet, but the first aerosol-generating device is aligned with the second charging device magnet. Latching will not occur when the aerosol-generating device is provided in an aligned configuration. This can advantageously ensure that latching takes place only in certain longitudinal orientations. This may be named self-keying.

Preferably, the magnets used for latching are rare earth magnets, for example high power magnets such as NdFeB magnets. High power magnets need only be small in size to hold the aerosol generating device and charging device.

The aerosol-generating device may remain engaged with the charging device by interference. For example, the distal end of the aerosol-generating device can engage the first end and the proximal end of the aerosol-generating device can engage the second end, between the opposite end of the device and the first and second ends of the charging device. The frictional engagement keeps the aerosol-generating device in engagement with the filling device. A biasing means, such as a spring, may be positioned on or at one end of the aerosol-generating device to help provide interference when the aerosol-generating device and charging device are engaged. The biasing means may also help to provide pressure between the contacts located on the aerosol-generating device and the contacts located on the charging device to increase the reliability of these contacts during engagement between the aerosol-generating device and the charging device.

The aerosol-generating device may include a charging contact located at or near the distal end, or at or near the proximal end, and the charging device may be positioned at or near the first end of the docking arrangement, or at or near the first end of the docking arrangement. 2 may include a corresponding charging contact located at or near the end. It may be advantageous if at least one charging contact is configured as a concentric ring at the end face of the aerosol-generating device, for example at the distal end face of the aerosol-generating device. Accordingly, the distal end face of the aerosol-generating device may include concentrically arranged first and second concentric electrical contacts, e.g., a concentric ring, wherein the first electrical contact is a positive contact and the second electrical contact is a negative contact. . One contact may be a point contact and the other contact may be a ring surrounding the point contact. A corresponding contact point, which may or may not be in the form of a concentric ring, may be defined at the first or second end of the charging device to allow electrical coupling between the aerosol-generating device and the charging device. The first or second end of the charging device may include first and second concentric electrical contacts arranged as a concentric ring, the first electrical contact being a positive contact and the second electrical contact being a negative contact. A corresponding contact point, which may or may not be in the form of a concentric ring, may then be defined at the distal or proximal end of the aerosol-generating device to allow electrical coupling between the aerosol-generating device and the charging device.

Alternatively, the filling contact may be configured as a circumferential ring substantially or entirely surrounding one or more body portions of the aerosol-generating device, such as a circumference near the distal end of the aerosol-generating device. Accordingly, the body of the aerosol-generating device may include first and second longitudinally spaced circumferential electrical contacts, where the first electrical contact is a positive contact and the second electrical contact is a negative contact. Mating contacts may be defined on the charging device to allow electrical coupling between the aerosol-generating device and the charging device.

The charging contacts may be arranged symmetrically on the body of the aerosol-generating device. For example, the first charging contact can be located midway on the body of the aerosol-generating device between the proximal end and the distal end. The additional contact points may be equidistantly spaced distally and proximally such that one of them is aligned with a corresponding contact point of the charging device, regardless of the longitudinal orientation in which the aerosol-generating device engages the charging device. Likewise, the charging contacts may be arranged symmetrically on the body of the aerosol-generating device such that one of them is aligned with a corresponding contact of the aerosol-generating device, regardless of the longitudinal orientation in which the aerosol-generating device engages the charging device.

The charging contacts allow data transfer between the aerosol-generating device and the charging device as well as charging of a secondary power source. Alternatively, one or more dedicated data transfer contacts may be defined on the aerosol-generating device and the charging device to allow data transfer between the devices.

The aerosol-generating system may include a means of wireless data transmission, such as a Bluetooth connection.

The aerosol-generating system may be configured such that the aerosol-generating device can be charged regardless of the longitudinal orientation in which it engages the charging device. In an advantageous configuration, the aerosol-generating device may include a charging contact located at or near at least one of the distal end or the proximal end, the charging device having a corresponding charging contact located at both the first and second ends of the docking arrangement. Contains charging contacts. Accordingly, even if the aerosol-generating device includes a charging contact only at one of the distal end and the proximal end, the electrical connection can be made regardless of the orientation in which the aerosol-generating device is presented to the charging device. Accordingly, if the aerosol-generating device includes a charging contact located at its distal end and the charging device includes corresponding charging contacts located at both the first end and the second end of the docking arrangement, then the aerosol-generating device has a first position where the distal end engages the first end of the filling device and the proximal end of the aerosol-generating device engages the second end of the filling device, or where the distal end of the aerosol-generating device engages the second end of the filling device and aerosol The proximal end of the generating device may engage the docking arrangement in any of the second positions where the proximal end engages the first end of the charging device. In this configuration, the user does not have to worry about accurately directing the aerosol-generating device to the charging device. This can be particularly advantageous when using the system in low light conditions. The aerosol-generating device may similarly have electrical contacts for charging a secondary battery located at both its proximal and distal ends, such that the aerosol-generating device may be connected to the secondary battery regardless of the longitudinal orientation in which the aerosol-generating device engages the charging device. Affects ability to charge power.

The system can be similarly configured so that any data connection between the aerosol-generating device and the charging device can be made regardless of the engagement orientation.
